What are the processes of weathering, erosion, and deposition in coastal environments, and how do they shape coastal landforms?
Understand the Problem
The provided text is an extensive overview of coastal processes, including weathering, mass movement, erosion, deposition, and coastal landforms. It also covers management strategies for coastal erosion. The key concepts include different types of erosion (hydraulic action, abrasion, attrition, corrosion), methods of sediment transport, and landform examples like wave-cut platforms, spits, and bars. The text outlines both hard and soft engineering approaches to manage coastal erosion.
Answer
Weathering breaks down rocks; erosion moves sediment; deposition settles it, shaping coastal landforms.
Weathering in coastal environments breaks down rocks through physical, chemical, or biological means. Erosion involves the removal and transportation of sediments by wave action, tides, and currents. Deposition occurs when these forces lose energy, causing sediment to settle and form various coastal landforms.

Deposition occurs when these forces lose energy, causing sediment to settle and form various coastal landforms.
More Information
These processes contribute significantly to the dynamic nature of coastlines, continuously reshaping them by forming features such as cliffs, beaches, spits, and barrier islands.
Tips
A common mistake is confusing weathering with erosion. Weathering only breaks down materials, while erosion involves movement.
